I found the stepped attenuators on the Mini Torii too coarse the get the exact volume I wanted. I'm using a CSP+ preamp to solve the problem. I might send my Mini Torii back to Steve and have a regular pot installed. Something to think about.

The DM945 speakers (in my too large room) have gorgeous upper midrange and treble. The lower midrange is unsatisfactory, and bass is MIA. Going from the Mini Torii to a more powerful 65 watt amp helped, but the sound is still a little thin and unbalanced. Good speaker, wrong room. The build quality and visual appeal of the DM945 is first rate.

Thanks for sharing your experience on the stepped attenuators and DM945. Since my Study is a small room, and I often work late, I need the fine control you mentioned. I have ordered my system (both the ZCD and Mini Torii) without the stepped attenuators.

I look forward to learning more about tubes, tube amps, and speakers from folks on this wonderful forum.
